If it’s just the battery then you should be able to confirm this if it works fine while plugged in via a wall wart. If it’s not then you might be able to revive it with tcctool and then check the battery.

Anyway, tcctool won't help if it doesn't come to life, so I bought a battery anyway and put it in myself. My life was beautiful again! BUT, about 4 days later it wouldn't come to life again. I tried about a dozen times plugging it in to different sockets and whatever. About the 12th time it worked?

i don't know - crazy as hell I tell ya.

It's not that hard to put the battery in and it really can't be done incorrectly, so my guess is a bad battery for some reason. But it's working now so ....I'll wait.

ONE thing though. I forgot how the D2 charging goes. Please tell me if a stock D2 while charging from the wall displays the charging screen the whole time or just at the beginning? Very important for me to know.

I don’t know cause I don’t own a D2 but my i7 while on wall wart displays a dancing battery filling up, while connected to pc it displays a USB icon rotating in a circular motion. The i9 on wall wart displays a charging icon with motion and goes dim after a few minutes. On the pc a motionless USB icon appears but only the i9 dims after a few minutes via either connection.

and i9 screens will either display the battery icon if connect via wall wart or go dim after a few minutes if connected to pc.

If your handy with a soldering iron it should be easy to replace(if it is the battery). If not then you can send it to me and I can solder it for you, visit the link in my signature to see my classified ad.

If we conclude the motherboard is dead then I am in need of a few D2 parts if you want to make a deal of sorts.

Also, if you do disassemble it yourself, then be cautious of the screws, they are VERY easy to strip on the D2, and other Cowon devices..
